This document provides a summary of upcoming workshops on Deltares hydrological software: - There will be 3 workshops on coastal flood forecasting using Delft-FEWS, river basin modelling using wflow, and the Adaptation Catalyst tool. - The workshops will include presentations on the software, exercises, and case studies applying the tools to locations around the world. - Delft-FEWS is a platform for flood forecasting that integrates data collection, model running, analysis, and emergency response. Wflow is an open source framework for hydrological modelling at the river basin scale. The Adaptation Catalyst tool supports decision-making for climate change adaptation pathways.

method for reducing the risk of loss of life
and economic losses”
Why Delft-FEWS?

5. • Detecting:
What is happening now?
• Forecasting:
What will happen in the future?
• Warning:
Is it going to be a problem?

27. Modelling inland water quality and emissions
• The hydrologic wflow_sbm model is now linked to D-Emission and D-Water Quality using a coupling script that:
• Translates wflow schematization to D-Water Quality schematization
• Prepares dynamic inputs needed for water quality modelling (different water fluxes and volumes, emission
factors)
• Is flexible enough to enable different types of pollutants emissions modelling

31. The
Adaptation Catalyst Tool

32. Adaptive Planning – What’s new?
What is not new?
• for centuries we adapted our delta to change
• but often in response to (near) disasters
What is new:
• anticipate the change (SLR-CC)
• but these changes are uncertain
• this requires new approaches and methods
Dealing with uncertainties is the key issue of adaptive planning:
• “what to do and when to do it?”
• “not too much, not too little”
• “not too early, nor too late”

An adaptation pathway map shows different
possible sequences of decisions to achieve
objectives. A scorecard helps to evaluate the
pathways and decisions.

35. • In water management we are facing an uncertain future
But we have to make decisions now:
Too early?
Too little?
Too late?
Too much?
• Dynamic Adaptation Policy Pathways
• Tools we are going to use:
Sustainable Delta Game (serious game about decision making under uncertainty)
Adaptation Catalyst (discussion support tool for developing sequences of interventions)
Pathways Generator (discussion support tool for visualisation of Adaptation Pathways)
